If complex regional pain syndrome isn't diagnosed and treated early, the disease may progress to more disabling signs and symptoms. These may include:

  • Tissue wasting (atrophy). If you avoid moving an arm or a leg because of pain or if you have trouble moving a limb because of stiffness, your skin, bones and muscles may begin to deteriorate and weaken.
  • Muscle tightening (contracture). You also may experience tightening of your muscles. This may lead to a condition in which your hand and fingers or your foot and toes contract into a fixed position.
